Josh has hiked 17 km, which is 2 km away from being 1/2 done. 
<span>In a equation, this might look like: 17 + 2 = (1/2)h </span>
<span>where h is the length of the hike. </span>
<span>and solve for h, h = 38 km

What is the area of this parallelogram?<br><br> 44 cm²<br><br> 55 cm²<br><br> 99 cm²<br><br> 220 cm²
Art [367]
Here, we can split this parallelogram into two triangles and one rectangle. The triangles are equal to each other so we can just find the area of the rectangle and the are of <span>one triangle. 

</span>Triangle area formula: a= \frac{1}{2} bh, where a = area, b=base, and h=height.

Plug in 5 for b and 11 for h:

\frac{1}{2}*11*5 =  \frac{55}{2}
<span>Multiply by 2!
</span>\frac{55}{2} *2=55

Rectangle area formula: a=bh, where a = area, b = base, and h = height.

Plug in 4 for b and 11 for h.

a = 4 x 11
a = 44

44+55 = 99

Area is 99 cm<span>².</span>

2. Mourette is a member of her high school golf team. She hits a golf ball
Llana [10]

Answer:

a. h = 60t − 4.9t²

b. 12.2 seconds

c. 183.7 meters

Step-by-step explanation:

a. Given:

y₀ = 0 m

v₀ = 60 m/s

a = -9.8 m/s²

y = y₀ + v₀ t + ½ at²

h = 0 m + (60 m/s) t + ½ (-9.8 m/s²) t²

h = 60t − 4.9t²

b. When the ball lands, h = 0.

0 = 60t − 4.9t²

0 = t (60 − 4.9t)

t = 0 or 12.2

The ball lands after 12.2 seconds.

c. The maximum height is at the vertex of the parabola.

t = -b / (2a)

t = -60 / (2 × -4.9)

t = 6.1 seconds

Alternatively, the maximum height is reached at half the time it takes to land.

t = 12.2 / 2

t = 6.1 seconds

After 6.1 seconds, the height reached is:

h = 60 (6.1) − 4.9 (6.1)²

h = 183.7 meters
